Series Description
The GAIA Converter HGMM-50 series designates a family of active power factor corrected AC/DC isolated modules designed to be compatible with the latest airborne input bus with single phase 115 Vac / 400 Hz variable frequency. This module accepts a variable frequency input from 360 to 800 Hz in the range of 95 to 140 Vac and an active power factor that enables a very low level of current and voltage harmonic distorsion over the entire frequency excursion. 
The HGMM-50 series is compliant with numereous avionics/military standards among them with: 
- the latest Airbus standards ABD100: 
. permanent input range: 108-122 Vac 
. transient: 71Vac/15ms - 180Vac/100ms 
. variable frequency: 360 - 800 Hz 
. power factor: 0.95 
- the international standard DO-160D: 
. permanent input range: 100-122 Vac 
. transient: up to 180Vac/100ms 
- the US military standard MIL-STD-704E: 
. permanent input range: 108-118 Vac 
. transient: 80Vac/10ms - 180Vac/100ms.
The HGMM-50 series includes a soft start, a permanent short circuit protection and an inhibit fuction. The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the module against short-circuits of any duration by a shut down and restores to normal when the overload is removed. 
The HGMM-50 series includes a model available with dual 2 x 17 Vdc outputs serialisable/parallable 17 or 34 Vdc to optimize the use of hold-up capacitance. 
The HGMM-50 series has to be used as front-end in conjunction with a capacitance for hold-up and DC/DC modules at the output. 
The design has been carried out with surface mount components and is manufactured in a fully automated process to guarranty high quality. Every module is tested with a GAIA Converter automated test equipment. The modules are potted with a bi-component thermal conductive compound and packaged in a metalic case to ensure the module's integrity under high environmental conditions.
